EXPANSIBLE WASHER.

of expansible washers and has for its object to provide a washer which,after adjustment to desired thickness, will have its parts firmlysecured in position and have the capacity for sustaining very heavyloads, and my invention, generally speakconsists of a washer made upoftwo or more parts or members screwing into each other and so formed thattwo of said members shall present opposed faces to each other in theinside of the washer and a supplemental washer of fusible metal fillingthe space between said opposed faces and opposing any collapsingmovement of the washer members. *lVly invention also includes featuresof construction of the'screw engaged washer members by 'which thepouring into plan of the supplemental washer member is facilitated andby which an interengagement of the supplemental and other washer membersis provided for and other details of construction.

The nature of my improvements will be best understood as described inconnection with the drawing, in which i Figure l is a central sectionalelevation of my washer shown as in use in support ing an engine bedplate on a sole plate.

Fig. 2 is a plan view of my washer with a bolt passing through it shownin section, and r Fig. 3 is a sectional elevation of a modified form ofmy washer.

A indicates the flanged edge of an engine bed plate having a bolt hole Aformed through it for a holding down bolt. B indicates a supportin soleplate in which is formed a bolt hole l3 in line with the hole A. D is afaced off portionof thesole plate surrounding hole B and affording aseat for the washer which is parallel to the I under face of bed plateA. C is a holding down bolt and C a nut screwing upon it. E indicates myexpansible washer in its preferred form, made up. of a part E in-Specification of Letters meat, tent J n 9 ,a iication filed my 28, 1919.Serial No. 360.472. I

ternally threaded, as shown at E, and havngan inwardly extending annularportion indicated at E E indicates an externally threaded washer memberscrewing into member E and having a face E lying opposite to face E. E,E indicate holes extending into the faces E and E and E E etc, indicatevent holes extending through thebody of'a' washer member from thechamber formed betweenthe two members. I E is a' slot formed in member Eto afford a holding shoulder for a turning tool. F indicates asupplemental washer of fusible metal which is run into the space betweenthe faces E and E and which made up i of two right and left threadedmembers G and G screwing into a sleeve nut G. Holes G are formed in theopposed faces of members G and G and vent holes G are provided, and, asin the other form of washer, a supplemental washer F is run into thespace between G" and G I I In using my washer, as shown in Fig. 1, thebed plate is carefully alined above the supporting sole plate and a bolthole A, B formed throughthem, the sole plate is then faced off aroundthe bolt hole, as shown at D, and the washer E, in collapsed position,is inserted and expanded to supporting position, as shown. '.Fi1siblemetal is then poured into the interior of the washer filling the spacebetween the faces E and E and the holes E anda portion at least of slotE where used, the vent holes E permittingthe air to escape freely. The

.bolt hole through parts A, B and washer metal through hole A,permitting it to.

fill not only the space between the opposed faces of the washer parts,but also some 'or all of the central passage through the -washer.

The method of securing bed plates and sole plates, briefly indicatedabove forms the subject matter of in application filed lMay 28, 1919,Serial 0. 300,471, and is not, therefore, claimed in this application.

It will be seen that the supplemental washer F, formed as abovedescribed, closes the space between the washer parts and forms a firmabutment for the opposed members which will prevent their approachingeach other either by a turning move.

ment or by strains, which tend to distort the threads, and, obviously,the interengagement of washer F with the washer members through theholes E and slot E will also tend to prevent any turning movement.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An annular washer consisting of relatively adjustable annular partsscrewing together so as to permit of variations in the thickness of thewasher,said washer having an internal space formed in it betweenadjustable parts thereof, and vent holes leading from said space throughthe body of a washer member. 5

2. An annular washer consisting of relatively adjustable annular partsscrewing together so as to permit of variations in the thickness of thewasher, said washer having an internal space formed in it lying betweenopposed faces of the adjustable parts thereof, andrecesses extendingfrom said internal space formed in the opposed faces of said parts. 3.An annular washer consisting of ad justable annular parts screwingtogether so as to permit of variations in the thickness of the washer,in combination with a supplemental annular washer of fusible metaliilling the space between the adjustable parts.

4;.A11 annular washer consisting of adjustable annular parts screwingtogether so as to permit of variations in the thickness 0f the washer,said washer being formed space between its parts and said adjustableparts being so formed as to provide interloekingrecesses in their innerfaces for a washer of fusible metal located between them, in combinationwith a supplemental annular washer of fusible metal filling the spacebetween the adjustable parts and proj ecting into the interlockingrecesses thereof.

6. n annular washer consisting of relatively adjustable annular partsscrewing together so as to permit of variations in the thickness of thewasher and the inner mem her or members being formed with a toolengaging slot in its inner periphery and the outer member with awrenchengaging outer surface, in combination witha supplemental annular washerof fusible metal filling the space between the adjustable parts of thewasher.
